Aaron Thurlow, Chief Commercial Officer at Caelux, about the company’s perovskite solar technology. Aaron shared his career journey from working at SunPower during its rise to market dominance to his current role at Caelux, where they are developing double-power-layer solar modules that can increase efficiency by 3% absolute (from 24% to 27%) while providing cost benefits including a 20% reduction in levelized cost of energy for utility-scale projects. They discussed the technical aspects of perovskite technology, including how it captures different parts of the solar spectrum that crystalline silicon cannot, and its potential applications in space, residential, and commercial markets. Aaron emphasized that efficiency remains the single biggest lever for driving down overall system costs and enabling 24/7 solar power through reduced storage requirements, positioning Caelux 's technology as a key enabler for the industry's continued growth and the transition to more distributed and localized manufacturing Topics Covered Caelux Commercial Readiness SunPower Market Launch Power Optimizer Origins Solar Efficiency History Solar Cost Reduction 24/7 Solar Future Localized Manufacturing Perovskite Dick Swanson Solar Glass Thin Film Space Based Solar Triple Junction Cells Silicon Efficiency Limits Energy Storage Integration CapEx = Capital Expenditure BIPV = Building-Integrated Photovoltaics HJT = Heterojunction Technology TopCon = Tunnel Oxide Passivated Contact DC = Direct Current NREL = National Renewable Energy Laboratory EV = Electric Vehicle   Reach out to Aaron Thurlow here: LinkedIn: www.linkedin.com/in/aaronthurlow Website: www.caelux.com Email: [email protected]   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean www.solarsean.com/esip

In this episode we have Shawn Shaw, founder and CEO of Camelot Energy Group, discussing energy storage and renewable energy development. Shawn explained how Camelot helps investors, asset owners, and project developers build reliable clean energy projects, highlighting challenges with community resistance to renewable energy installations including over 200 energy storage moratoria across the United States. The conversation covered technical aspects of energy storage safety, with Shawn sharing that commercial and utility-scale batteries experience fires at approximately 0.3% per year, similar to residential house fires, and discussing how safety standards have improved significantly since incidents like the Moss Landing fire. They also explored historical perspectives on energy storage, from medieval mill ponds to modern battery technology, and discussed how energy storage benefits extend beyond renewable energy integration to improving grid reliability regardless of energy source. Shawn mentioned his recent book publication on energy storage systems by the International Code Council and his work training professionals through Heat Spring platform, while both participants agreed to potentially collaborate on future podcast episodes covering the history of energy storage Topics Covered Camelot Energy Group www.camelotenergygroup.com Moss Landing Incident Thermal Runaway History of Energy Camelot Name Origin King Arthur Inspiration Medieval Energy Storage Mill Pond History Genghis Khan Energy Firefighter Training Project Development Investor Decision-Making Clean Energy Mission Big Bang Philosophy Electricity Bill Costs Grid Infrastructure Overbuilding BESS = Battery Energy Storage System AHJ = Authority Having Jurisdiction UL 9540A Reach out to Shawn Shaw here: LinkedIn: www.linkedin.com/in/shawnshawpe Website: www.camelotenergygroup.com Email: [email protected]   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean www.solarsean.com/esip

This podcast interview featured Maxim Kosenko, CEO and founder of Axentum, discussing their innovative technology for autonomous solar installation for AI data centers. Maxim explained their system uses flat, zero-degree tilt solar panels with pre-assembled PV modules and battery packs (2- 3 kWh per module) connected in strings to create 0.9-megawatt DC clusters that can be installed by four-person teams in under two hours, enabling installation of a gigawatt-scale project within a month using approximately 12 teams. The system eliminates traditional tracking systems, uses ballasted mounting instead of piles, and includes integrated battery storage and power electronics, resulting in a levelized cost of electricity around $50 per megawatt hour (5 cents per kilowatt hour) and potentially dropping the cost five times lower than current solar options for data centers.   Topics Covered Axentum www.axentum.com Autonomous Solar Installation AI Data Centers Megawatts per hour Installation Robot ESS = Energy Storage System Flat Panel Design Integrated Battery Storage Robot Deployment Installation Speed Wind Resistance Design Vegetation Prevention Labor Reduction Gas Turbine Shortage Solar vs Turbines Gigawatt Scale Buildout Power Electronics Embedded   Reach out to Maxim Kosenko here: LinkedIn: www.linkedin.com/in/maxkosenko Website: www.axentum.com Email: [email protected]   Learn more at www.solarSEAN.com and be sure to get NABCEP certified by taking Sean’s classes at www.heatspring.com/sean www.solarsean.com/pvip
